Modify and Replace Lyrics in Suno AI: A Practical Guide

You’ve just generated a fantastic song in Suno AI. The melody is catchy, the instrumentation is perfect, but there's one small problem: a word or a line in the lyrics isn't quite right. Maybe it doesn't fit the mood, or perhaps you've thought of something better. For instance, you have:

[Verse] I need the stars to align tonight

But you want to change "need" to "greed" to give the song a darker, more dramatic edge.

Don't discard the whole track! Modifying specific lyrics is a common challenge, and with the right techniques, you can fine-tune your song to perfection. Here’s how you can effectively replace or modify lyrics in your Suno AI creations.

Method 1: The "Extend" Feature for Lyric Infilling

This is the most direct method within Suno for replacing a section of lyrics while trying to preserve the surrounding musical style. Think of it as telling Suno, "Continue the song from here, but use these new words for the next part."

Here's the step-by-step process:

1. Generate Your Song: Create your initial two-minute song and identify the part you want to change.

2. Initiate the Extension: Find your generated song in your library and click the "Extend" button.

3. Set the Context: In the "Extend From" time input, set the timestamp to the beginning of the lyrical section you want to replace. For example, if the line "I need the stars to align tonight" starts at [00:15], you would set the extend point to 00:15.

4. Provide the New Lyrics: In the lyrics box, paste the lyrics you want for the new section. It's crucial to also include the lyrics from the section immediately preceding it to give Suno musical context. This helps maintain a consistent melody and vocal style.

   Example Prompt for Extending:

   [Verse]
   The city sleeps beneath a velvet sky
   
   [Chorus]
   I greed for the stars to align tonight
   A cosmic dance in pale moonlight
   

   In this example, Suno uses the preceding [Verse] as a reference before generating the [Chorus] with the new word, "greed."

5. Generate and Stitch: Click "Extend." Suno will generate a new clip starting from your specified point. Once you have a version you like, you'll need to use simple audio editing software (like Audacity or CapCut) to stitch the original part of the song together with your newly generated, corrected segment.

Method 2: Create an Instrumental and Re-Vocalize

If the "Extend" method isn't giving you the desired result, or if you want to replace all the vocals, this advanced technique offers maximum control. The process involves separating the music from the vocals and then having Suno create a new vocal track over the original instrumental.

1. Create an Instrumental Version:

   • In Suno: Generate a new song using your original style prompts but add [Instrumental] or [No Vocals] to the lyrics box. This tells Suno to create only the music.
   • With External Tools: If you already love the music of a generated song, use a stem separator tool like Moises.ai or LALAL.AI. These services can take your song file and split it into separate tracks (vocals, drums, bass, instrumental). Keep the instrumental track.

2. Add New Vocals in Custom Mode:

   • Navigate to Suno's Create page and switch to Custom Mode.
   • Turn on the "Instrumental" toggle and upload your instrumental audio file.
   • In the "Lyrics" box, paste your complete, corrected lyrics.
   • In the "Style of Music" prompt, describe the vocal style you want (e.g., "ethereal female vocals, pop ballad").
   • Click "Create." Suno will now generate new vocals based on your lyrics over your pre-existing instrumental track.

Key Tips for Success

• Small Changes Work Best: The "Extend" method is most effective when you're changing only a few words or a single line. Rewriting an entire verse can sometimes alter the melody more than you'd like.
• Maintain Rhythmic Structure: When replacing words, try to use new words with the same number of syllables and a similar cadence to the original. This makes it easier for the AI to fit them into the existing melody.
• Patience is a Virtue: AI music generation is an iterative process. Don't be discouraged if your first attempt isn't perfect. Experiment with slightly different timings or phrasing in your prompts. Each attempt can get you closer to your ideal song.
